Request Information
RKI's Model EC-600 is an indoor, standalone monitor that detects Carbon Monoxide (CO) with a range of 0 to 150 ppm with 1 ppm increments. It's sleek, low-profile design is equipped with a unique tri-color display, which changes color as Carbon Monoxide levels reach each alarm level. It is capable of operating with three different power options; 115 VAC, 24 VDC or alkaline batteries. The EC-600 has two preset alarms, and comes ready to operate with a simple wall mount bracket and 10 foot power cord in its AC version.
